Default '98 A4 1.8T Mystery Oil Leak..

I had posted a week or so ago about a sudden oil leak in my car, checked everything that everyone suggested..

So basically after jacking up the car, what I'm seeing is the downpipe is getting wet from the joint to the turbo... AND the heat shield on the right side of the downpipe is covered with fresh oil. The turbo is dry, and the oil lines look good. the area after the turbo in the cat area is clean, its all after the cat that is wet. The back of the engine is dry, the lower right corner of the valve cover is a little wet, but there's no way it could be the valve cover because it is not wet directly below at all (cat area) it is much farther back.

It does not leak at idle or revving in park, only after driving around the block does it start leaking. I don't see any oil lines that far back, so the only thing I can think is that the oil starts spraying out from somewhere after driving or under boost.
I took the intercooler hose off, but there wasnt any oil as if the turbo seals were leaking, and the engine doesnt smoke out the tail pipe.

Clean everything up, add enough oil, take it for a drive and come back. Check again, and be sure to take some oil with you on the drive.

Check you PCV system: if the lines get clogged, pressure builds up inside and will start causing leaks.
